Kagawa has been out for some games due to injury. Cazorla has played many good games, but many that were kind of poor for him. Hazard may be the best of them three, but the fact that Chelsea play with a bad striker at least half of the time means that his contributions have been greatly for nothing.

Kagawa only played 10 games. Not even half as many as the other two, not even got going yet! He has looked great in quite a few of them but United have played him in a quantum shift in their formation (virtually a 4-3-3) which also would need some adapting.

Cazorla looks like a great player as well and a good buy, he is instantly one of Arsenal's best players IMO now that Song and RvP have left.

Eden Hazard is a real class act and will be a brilliant player in a couple of years for sure. As you say however, he has to find his favoured place in the lineup.

They are all close. Because of the few games Kagawa has played he can't really be included in the comparison very well.

That means Cazorla v Hazard. Its kinda a whitewash in terms of ability shown so far, however because Cazorla seems cheap for what Arsenal paid and Hazard was twice as expensive, Cazorla edges it for me. Hazard will prove to be worth his fee in the long run- Cazorla has already.

It doesn't mean I would take Cazorla instead because he is a lot older which accounts for the fee differential, but he just edges it the teeniest amount this half of the season.
